Officers said Julie Mitchell's stepson found her body inside their home around 10:20 p.m. Tuesday.

Officers said during a 911 call, the stepson told police he thought it was a suicide, but police later found "suspicious things" inside the house that led them to determine it was a homicide. Investigators said they spent 19 hours scouring the crime scene for evidence.

Teddy Mitchell's lawyer said Mitchell had to charter a plane in Arizona to get home as quickly as possible once he discovered what had happened at his home.

Mitchell's lawyer said the family is dumbfounded and absolutely devastated. Police have questioned several people, including Teddy Mitchell, but said that was part of an effort to gather information.

Police have not revealed how Mitchell died or who may have been home at the time of her death. An autopsy was performed on Thursday, but details of the findings won't be released until Friday.

A key question, police said, is determining the exact time that she died.

Teddy Mitchell offered thanks on the family's Facebook page to the people who have posted messages of condolence. The couple's 13-month-old daughter is staying with family members.
